Additional information

Conclusion on classification

Based on the LC50 result in the 96h acute toxicity to fish test (27.8 mg/l for the read-across substance linalool) and confirmed ready biodegradability, the classification of dihydromyrcenol is concluded to be:

- under Directive 67/548/EEC criteria, not classified

- under Regulation 1272/2008 (CLP GHS) criteria, not classified

- under UN GHS criteria, acute aquatic hazard category 3.
